    Rated 4 out of 5 by Quick availability saves the day I had to kick start my Vespa on a few damp mornings during the summer. I should have ordered a battery immediately. I didn't, so on a Thursday night at 7pm in a damp, dark car park it died completely and wouldn't kick start and I had to call the AA to get me going. If you order batteries via most online outlets they take a few days to arrive and then you have to charge them. I was delighted to find Halfords had scooter batteries and bike chargers. I reserved online at 11pm on a Thursday night and collected after work on the Friday. Putting the acid into the battery is a bit of a fiddle, I overfilled and had to remove some with a medical syringe. I struggled to see the levels. The instructions on the packet are poor but You Tube has some good videos for a beginner. I understand that once filled and ready the battery will start a bike, but most biker/dealer sites advise you to trickle charge the battery to get it to full power and to ensure the battery has a long life. I didn't realise that scooter batteries need much more love and attention than a car battery. There's some great info online so I hope to have uninterrupted riding wit battery issues in future. Well done Halfords for such quick service and availability at a good price. 16 August 2015

    Rated 5 out of 5 by Back on the Road My daughter's scooter died on her. As we had been having problems with her battery I looked on-line and reserved one at my local Halfords to be collected that day. The battery was waiting for me to collect, plus I had some useful advise from the assistant on what to do with the battery, which involved adding the acid and charging. I didn't even have to ask, he offered it to me. The battery has put my daughter back on the road again, simply, easily and without fuss thanks to Halfords 03 January 2015

    Rated 5 out of 5 by Works fine. Not much I can say after few weeks of use. After filling with acid and charging my scooter started straight away and everything works as is should so far. 20 October 2014
    Rated 4 out of 5 by Perfect substitute for OEM item. I bought this item to replace the dead battery on my son's old quad bike. It dropped straight in and did the trick. Replacement item from the manufacturer was double the price of this battery. It makes sound economic sense to me. 17 August 2014
